As shown in FIGURE 1 the enlargement 15' of the barrel 14is adapted to engage a shoulder portion 26 on the base 12 so as to helpprevent accidental shifting or movement of the syringe.

The numeral 27 indicates an upwardly inclined projecting arm or supportmember that is secured thereto or formed integral with the base 12, andas shown in FIGURE 1 an end piece 28 is arranged at right angles withrespect to the support member 27, and the end piece 28 is secured to thesupport member 27 as for example by means of screws or securing elements29. The support member 28 is provided with openings 30 therein, and thenumeral 31 indicates a receiver that is arranged contiguous to the endpiece 28. The receiver 31 includes a body portion 32 as well as a wallsection 33 that has an integral flanged portion 34 for snugly receivingtherein the head 21 of the plunger 20.

There is further provided a clamp which is indicated generally by thenumeral 35-, and the clamp 35 embodies a bracket that includes legs 36and 37 that are arranged at right angles with respect to each other,FIGURE 4, and the clamp bracket 35 is secured to or formed integral withthe portion 23 of the base 12. The numeral 38 indicates a screw memberthat is adjustably connected to the portion 37, and a knurled element 39on the screw member 38 facilitates the manual adjustment thereof. Thenumeral 40 indicates an arcuate saddle or yoke that is connected to thelower end of the screw member 38, and the saddle 40 is adapted to engagethe barrel 14 of the syringe 13.

The numeral 41 indicates a flexible cable that includes an outersheathing 42 that is connected to a fastener 43, and the fastener 43 maybe firmly affixed to the end piece 28. A flexible wire 44 is slidable inthe outer sheath ing 42, and the wire 44 may have an end thereof peenedover or flattened as at 45, and also a portion of the wire 44 may beflattened as at 46. This construction, that is the provision of theenlarged or flattened portions 45 and 46 serves to insure that thereceiver 31 will be firmly affixed to the sliding inner wire 44 of theflexible cable 41 so that as this wire 44 is moved, the receiver 31 willbe moved in order to reciprocate or move the plunger 20 into or out ofthe barrel 14 of the syringe 13.

The numeral 47 indicates a manually operable actuator which includes athumb piece 48 as well as a rod-like portion 49, and the rod-likeportion 49 is provided with calibrations or indicia thereon, as forexample as shown in FIGURE 1.

As shown in FIGURE 1, there is provided a hand gripping element 50 whichis suitably aflixed to the sheathing 42 of the flexible cable 41, andthe hand gripping element 50is provided with finger engaging lugs 51thereon.

From the foregoing, it is apparent that there has been provided asyringe holder or support, and in use with the parts arranged as shownin the drawings, it will be seen that the stand or holder 10 is adaptedto be arranged in a convenient location such as in a position adjacentto a patient being treated or examined in a hospital or the like, andthe horizontally disposed platform 11 provides a firm support for thebase 12 which extends upwardly from the platform 11, and the base 12 isprovided with the inclined upper portion 23 that has the support memberor arm 27 inclined upwardly therefrom. The end piece 28 is fastened asat 29 to the support member 27, and the syringe 13 is adapted to bearranged as shown in FIGURE 1 so that the barrel 14 of the syringe 13 issnugly received in therecess 24 of the base 12 and the abut or engagethe stop shoulder 25 formed on the base 12. The enlargement 15 on theother end of the barrel 14 is adapted to engage the portion 26 of thebase 12, and these parts together with the clamp means 35 insure thatthe syringe 13 will be properly held in position as it is actuated. Theclamp '35 includes the member that consists of the right angularlyarranged portions 36 and 37, and the screw members 38 extended throughthe portion .37 is arranged in threaded engagement therewith, so that bymanually rotating the knob 39, the screw member 38 can be rotated oradjusted in order to move the arcuate saddle 40 into or out of clampingengagement with respect to the barrel 14 of the syringe 13. The syringe13'includes the usual sliding plunger 20 as well as the tip 16 that isprovided with the stop cock 17, and the stop cock 17 as shown in FIGUREincludes the opening or port 19 which can be moved into and out ofopened or closed position as for example by manually moving the handle18.

The head portion 21 of the plunger 20 is snugly received in the receiver3-1, and it will be noted that the receiver 31 is shaped to include thewall section 33 as well as the flanged section 34 whereby the headportion 21 of the plunger 20 can be readily disengaged from the receiveror arranged in engagement with the receiver. The receiver 3 is firmlyaihxed to the sliding inner wire 44 of the flexible cable 41, and thisis accomplished in any suitable manner, as for example by peening overportions of the wire 44 as indicated by the numerals 45 and 46 so thatthe receiver 31 will be securely aflixed to the sliding wire '44. Thus,as the wire 44- is moved back and forth Within the sheathing 42, thereceiver 31 will be moved back and forth so as to cause the plunger 20to be moved relative to the stationary barrel 14. This movement of theplunger 2%) can be used for the usual purpose, that is for dischargingthe contents of V the syringe 13 out through the tip 16 or the like.

The present invention includes a remotely operated means whereby theplunger 20 can be moved from a remote location so that it is notnecessary for the user to manually grip the plunger 20 and move the samesince this movement of the plunger can be accomplished from aconsiderable distance spaced away from the syringe. This remoteoperation can be brought about by manually gripping the'element 50, andthen manually moving or pushing on the finger piece 48 whereby with therod-like clement 49 secured to the inner sliding wire 44, it will beseen that this relative movement between the elements 48 and 50 willresult in the wire 44 sliding in the outer sheathing 42, and since thewire 44 is secured to the receiver 31, it will be seen that this willcause corresponding movement of the receiver 31 so as to move theplunger 20. The portion 49 of the actuator 47 is adapted to be providedwith indicia or 'scale markings thereon, as for example as shown inFIGURE 1 so that the person operating the syringe from a remote locationcan accurately observe or determine the exact quantity of material beingdispensed or discharged from the syringe.

The partscan be made of any' suitable material and in different shapesor sizes. 7 7

The primary purpose of the present invention is to protect medicalpersonnel from the hazards of X-radiation during specializedexaminations such as cerebroangiograms, angicardiograms and all othertypes of venograms and'arteriograms. With the present invention aneurosurgeon or the like will have a compact and uninvolved dependableand completely eflicient manually operable injector which includes orincorporates the safety factor of distance as protection from a rapidlyfiring source of radiation;

The present invention includes the very simplebase 12 for the attachmentof a Robbssteinberg syringe 13 which in turn is operated at the otherend of a cable 41 which may be a steel cable seven feet long or thelike, although the length of the cable can be varied as desired orrequired, and this cable 41 includes a flexible sheathing 42. The filledsyringe 13 is adapted to be laid on the base and the head of the plungeris placed in the metal receiver 31 so that by twisting the thumb screw38, the syringe will be stabilized.

The fifty degree angle angle of the syringe is believed tobe optimum foreither withdrawal or injection, and such an angle has been ascertainedfrom experiments to be advantageous. The Robb-Steinberg syringe 13 maybe a 50 cc. syringe and is generally of the same construction as anyother 50 cc. syringe except that the tip 16 has a greater lumen (12G) tofacilitate the rapid injection of a radio opaque contrast medium. Rapidinjection in conjunction with rapid radiation exposures is necessary inorder to properly visualize or rule out lesions in the circulatorysystem of the human body.

The simple construction and assembly of the present invention insuresthat the same can be produced economically, and its ease of storage andreplacement of parts makes the same readily available to all hospitalsand institutions. In addition, there is no explosion hazards and itssympathetic operation is as sensitive and 'efiicient as the personoperating the unit.

The device although herein described in conection with X-radiationexaminations is easily adaptable to other forms of research, especiallyradioisotopes, and it can also be used either as a safety feature orwhere effective sensitiveness at a distance is required in otherindustries.

In addition, the flexible cable 41 which may be approximately seven feetlong can be rolled up and tied to the base or detached for storage orreplacement, as for example due to the provision of the screws 29 whichpermit separation of the parts. The element 49 is adapted to have thescale markings thereon which may be marked every 432" of an inch apartso as to indicate 5 cc. of solution injected. The head 21 of theRobb-Steinberg syringe plunger 20 is adapted to be inserted in thereceiver 31 as shown in the drawings. The syringe 13 is shown in FIGURE1 arranged at an angle of fifty degrees. The design of the base 12 canbe optional except for catheter clearance, and the unit should weigh atleast fifteen pounds for stability.

The present invention is not restricted to any particular used inconnection with the taking of pictures for medical case histories or thelike as for example when a catheter is used, and wherein a dye may beinjected under pressure. The stop cock 17 may be used in conjunctionwith angiocardiograms, and the syringe can be used for injecting varioussubstances into veins in the patients arms or the like.

It is to be understood, that even though there is herein shown anddescribed a preferred embodiment of-the invention the same issusceptible to certain changes fully comprehended by the spirit of theinvention as herein described and the scope of the appended claims.
